List of Famous people born in Alaotra-Mangoro

Rainivoninahitriniony (1824–1868), was Prime Minister of the Kingdom of Madagascar between 1852 and 1864. He was the chief engineer of the Aristocratic Revolution initialized upon the attempted assassination of King Radama II. His excesses and participation in the regicide saw him fall from favor, ultimately being relieved of his position and replaced as Prime Minister by his younger brother Rainilaiarivony. Rainivoninahitriniony died in exile on May 5, 1868, shortly after an attempted coup meant to enable him to regain his position upon the death of Queen Rasoherina ended in failure.

Rainilaiarivony was a Malagasy politician who served as the prime minister of Madagascar from 1864 to 1895, succeeding his older brother Rainivoninahitriniony, who had held the post for thirteen years. His career mirrored that of his father Rainiharo, a renowned military man who became prime minister during the reign of Queen Ranavalona I.
